Damn mirror neurons... you happy

Wasn't there an episode/issue of Batman where the Joker poisons a subway car with laughing gas?

I would be that guy there that does not give 2 shits.

Flah mob laughing!

They all must have read one of QM's political comments

Or just the first woman.

Its all fun and laughter until the first person throws up from laughing too hard. Then everyone is throwing up.

Until the 1st person slips and falls on the vomit and then everybody starts laughing all over again.

*lies

I was looking forward to a good 3-minute laugh. Alas, none was had.

It's all fun and games till someone looses and eye - then it's hilarious!

Somebody fart?"

Wtf is this? It seems forced and awful. A few people trying a social experiment?

it's spelled "lose", not "loose". *ducks*

Wow, really?
I got a down-vote for a typo?

Notice how we can't go back and edit/fix our typos after one day.
There's going to be a lot more of these. Are we down-voting all typos now - Just so I know - because I have a lot of work to do if we are.
